MAINE, ASSIGNOR OF ONE-HALF I-IIS RIGHT TO GEORGE C. FRENCH, OF SAME PLACE.

IMPROVEMENT lN CAR-BUFFERS.

Specification forming part of Letters Patent No. 150,125, dated April 28, 1874; application filed April 7, 1873.

To all whom it may concern:

Be it known that I; EZEKUEL W. BA umn, of Portland, in the county of Cumberland and State of Maine, have invented eert-ain new and useful Improvements in Oar-Couplings and Buffers; and I do hereby declare that the following' is afull, elealgand eXaet description thereof, that will enable others skilled in the art to which it appertains to make and use the same, reference being had tothe accompanying drawings, and to the letters of referenee marked thereon,` which form a part of this specification.

Figure l is an end View of a platform, 'with a draw-head and buffer attached, Fig. 2, a top plan of a platform, showing the buffer.

My invention relates to an improved earbuffer. It consists of an improved buffer attaohed to the front of the platform.

P is the buffer, set on a stock, 1*, moving in and out in an aperture out for it in the front beam or wood-work of the platform s. It is also Connected With'a spring, t. This spring is made of metal, and is slightly curved in form, as shown. Its ends are held in sockets o, so as to admit of their movement or play as the spring is bent back toward the edge of.

the platform, or its curve ilattened, and as it resumes its shape again. rlhus, as the platforms of two ears come together, the buers P will strike each other, and the shook or jar be mitigated, and, in a degree, removed from the ends of the platforms by the spring t. It is plain that the more the spring t is attened or bent back the stiffer it becomes, andthe greater its resistance.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-

The buffer I), stock r, spring t, and sockets o, in combination with a ear-platform, as set forth.

In testimony that I claim the foregoing I have hereunto set my hand.
